The Last Lecture by Randy Pausch

I've heard of that book (haven't read it yet), but when it comes to something like that it's a very personal thing and, unless she's expressed a desire to you to read it, I'd pass.

Is your friend's relative a spouse or close family member? Will she end up being a caretaker of this person? You might wait and give her the gift of time, later on - when she will need respite from her relative's illness.

My dad has terminal cancer and my stepmom is his primary caregiver. Sometimes she just needs a break. Your friend may, too.

I know what you mean here, I was in a similar circumstance.  Tread carefully and don't do anything without some form of approval first - just in case.  It is a sensitive topic for all involved.  If you're friend is more directed towards cancer treatments have a look at this site Heal Your Cancer .  There is a compilation of books of other people's true stories as well as some alternative methods.  It may be helpful for you or your friend.
